What system is designed to provide circulating feed from several mains?

• A. Grid system
• B. Loop system
• C. Branch system
• D. Distribution system

Answer: (A)

The grid system is designed to provide a reliable and efficient means of distributing water by connecting multiple sources and mains in a network. This interconnected design allows water to flow from several directions, ensuring that if one supply line is compromised, alternate routes can still deliver water. The grid system enhances system resilience, allows for redundancy in supply, and can improve flow rates and pressure stability, making it particularly suited for urban environments where high demand or varied topography exists. In contrast, the loop system operates on a principle of creating a circular flow path, which can also provide redundancy and maintain pressure; however, it is generally less flexible than a grid system in terms of maintaining circulation from multiple mains. The branch system typically features a main line with offshoots leading to various endpoints, which can potentially create vulnerabilities if a primary line is interrupted. The distribution system, while a broad term that can encompass various methods of delivering water, doesn't specifically focus on the advantages of utilizing multiple mains, which is a defining feature of the grid system.
